Subjectively, we experience a stable representation of the outside world across saccades. Although previous studies have reported that presaccadically acquired visual information influences postsaccadic perception, whether such information's priority to access visual awareness is either reset by each saccade or continuous across saccades remains unclear. To investigate this issue, we combined a breaking continuous flash suppression (b-CFS) with a saccade task. Before each saccade, a grating was presented in the peripheral visual field under suppression. After the saccade, the same grating was again presented under suppression at either the retinotopically matched, the spatiotopically matched, or a control location. By measuring the duration of the grating to break through CFS into awareness after a saccade, we could compare the breakthrough times across stimuli presented at the different locations. No difference in the reaction times between the spatiotopic and control location was observed, indicating that a saccade resets the buildup of an object's priority to access visual awareness. However, a longer breakthrough time was observed for the retinotopic as compared to the control location, suggesting that a form of retinotopic adaptation to the grating suppressed the priority to access visual awareness after a saccade.

搜寻将视觉信息的优先级重置为访问意识。

从主观上讲,我们在各种扫视中都经历了稳定的外部世界代表。尽管以前的研究报告说,预先获取的视觉信息会影响术后的知觉,但是尚不清楚这些信息获取视觉意识的优先级是由每个扫视镜重置还是由各个扫视镜连续获取。为了研究此问题,我们将突破性的连续闪光抑制(b-CFS)与扫视任务相结合。在每次扫视之前,在抑制状态下,在周边视野中出现了一个光栅。扫视之后,同一光栅再次受到抑制,出现在视网膜局部匹配,空间分布匹配或控制位置。通过测量光栅的持续时间,可以在扫视后突破CFS的意识,我们可以比较在不同位置呈现的各种刺激的突破时间。在空间位置和控制位置之间没有观察到反应时间的差异,这表明扫视重置了对象获得视觉意识的优先级。但是,与控制位置相比,观察到视网膜裂变的时间更长,这表明视网膜裂变适应光栅的形式抑制了扫视后获得视觉感知的优先权。
